SPECIFICATION forming part of Letters Patent No. 696,749, dated April 1,1902. Application iiled September 11,1901. Serial No. 75.03B. (Nomodel.)

To rtZZ whom it may concern:

Be it known that I, CLARK F. RIGBY, a citizen of the United States,residing at New Martinsville, in the county ot Wetzel and State ofWestVirginia, have invented certain new and useful Improvements inGuides for Oil-Well-Pump Rods, ot` which the following is a specication,reference being had therein to the accompanying drawings.

In operating oil-Well pumps by means of wire or other cables the greatlength of cable connecting the walking-beam and pump twists on thedownstroke and untwists on the upstroke, causing thevertically-reciprocating pump or pump-plunger to constantly and rapidlyrotate, causing it to wear rapidly and reducing or destroying itseiiiciency. Also in this twisting and untwisting there is considerablelost motion, as the length of cable is constantly varying. Up to thepresent time strings of sucker-rods have been more generally used thancables for operating deep-well pumps; but with these also thereisatendency to turn or twist, resulting notinfrequently in the rodsparting, necessitating expensive iishing operations.

The present invention is designed to obviate these difliculties and torender the operation of pumping more certain and effective by providingmeans for holdingr the pumpactuating means from rotating or twistingwithout interfering with its vertical reciprocations.

Theinvention consists in the novel features of constructiomand in thecombination and arrangement of parts hereinafter fully described andclaimed, and illustrated by the accompanying drawings, wherein- Figure lis a vertical sectional view of my improvement in position in awell-tube. Fig. 2 is a side elevation of the same. Fig. 3 is an invertedplan view of the same on line 3 3 of Fig. 2. Fig. 4. is across-sectional view on line 4 i of the same figure.

Referring to the drawings, 2 represents a portion of a well-tube, and 3a rod angular in cross-section and of greater length than the stroke ofthe pump or pump-plunger 4, a portion of the latter being shown in Fig.l and uniting with the lower enlarged endV 3 of the rod. The upper endof the rod unites with socket 5, to which the pumping-cable is se-Loosely mounted on rod 3, so that the latter may reciprocatetherethrough, is tubular body 6, having an angular bore or passagecorresponding to the rod and at its upper end formed with head 7, towhich are secured the upper ends of the outwardlybowed leafsprings 8.The lower ends of the springs are secured to head 9, verticallyadjustable 'on body 6 by means of nut 10, operative on the lowerthreaded end 6 of the body. A lock-nut 10 may be provided for nut l0.IIead 9 is prevented from turning by spline 1l. Upward movement of head9 increases the outward bow of springs 8, and a reverse adjustmentreduces the same, as will be understood. By this means the springs arecaused to bear with a greater or less pressure against the inner surfaceof tube 2, gripping the same in such manner as to prevent rotation ofrod 3 and the actuating means coupled thereto, whether a cable or rods.

Before the pump is inserted in the well the holding device is positionedon rod 3 and adjusted as required. Then as the pump is lowered it isforced downward through the tubing by being engaged by the socket or rodcoupled to the upper end of rod 3 and in this manner brought to positionimmediately1 above the permanent position 0E the pump. Then the pump isremoved, the enlarged lower end ot' rod 3 engages and lifts the holdingdevice from the tubing. 1With the opposite ends of the springs drawninward the device may be thus readily inserted and removed.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

l. Means for holding deep-wellpumps from rotating comprising a bodyhavinga vertical' passage-way, said passage-way being of such form as toprevent rotation of the pump-rod which reciprocates therethrough, andtubeimpinging springs projecting laterally from said body, said springsbeing of sufficient strength to resist rotation of the pump-actuatingmechanism and pump.

2. Means for holding deep-well pumps from rotating comprising a ,bodyhaving a vertical passage-way, said passage-waybeing of such.

form as to prevent rotation ofthe pump-rod which reciprocatestherethrough, and elongated outwardly-bowed springs secured at theirends to the body, said springs being adapted to impinge the well-tubeand resist rotation of the pump -actuating mechanism and pump.

3. Means for holding deep-Well pumps from rotating in the well-tubingcomprising a device adapted to frictionally engage the interior surfaceof the tube, said device having a vertical passage-way of such form asto prevent rotation therein of the pump-rod which reciprocatestherethrough, and means for varying the frictional engagement of saidde- Vice with the tube.

4. In a device of the character described, the combination of adeep-well-pump-actuating rod angular in cross-section, an elongated bodyhaving an angular passage through which the rod reciprocates, said bodybeing threaded at one end, lelongated outwardlybowed tube-impingingsprings secured at one end to the body, a non-rotatable head slid ableover the threaded portion of the body and to which the opposite ends ofthe springs are secured, and a nut adjustable on the body for securingthe said head,substantially as shown and described.

5. In a device of the character described, the combination of apump-actuating rod angular in cross-section, a body having an an-l gularpassage through which the rod reciprocates, a resilient tube-impingingdevice carried by the body and adapted to be projected laterally bybeing contracted, and means for contracting said device, substantiallyas shown and described.

6. The combination of a rod adapted to be interposed between a deep-wellpump and its actuating means, an elongated non-rotatable body throughwhich the rod is adapted to reciprocate, outwardly bowed leaf sprin gssecured at one end to the body, and a head vertically adjustable on thebody to which the opposite ends of the springs are secured.

In testimony whereof I aix my signature in presence of two witnesses.
